BOOIQPAGE INDICATOR AND RETJPJNER.

Application filed April 30,

This invention relates to a not and. useful appliance .in the nature or a hook page indicator and retaining device especially adapted to be roniovahly attached to a hook as a means of holding the pages of a book in an extended position when the hoolt is open, eliminating the necessity of manually holding the pages. The said device is also adapted to nerve as a hook page indicator or hook mark when the look is in a closed position. 2

The object oi? the invention is to provide a device oi the class described of novel construction and arrangement of parts hereinafter more fully described, claimed and, il

a lustrated in the accompanying drawing.

As here embodied my improved hook'pagc indicator and retaining device comprises a. bracket 10 provided with a pair of side extended elements 11 and 12 formed or hent at approximately a right angle to the mainportion oi the hracketlO. The bracket 10 is alsoprovided \v1th acenter extended element 1928. Serial No. 274;,1 l8.

13, formed or bent similarly to the above men tioned elements 11 and 12and positioned intermediate thereof, SOIllBWlllll; above the elements 11 and 12. i

The above described construction such as will permit the side extended elements o'r the bracket to slidahly engage inside the upper portionoi the binding 14 of a hook inter mediate the covers 15 and 16 ot' the said hoolq the center extended element of the bracket slidahly engaging outside the said upper portion of the minding, as a means of reinovahly holding my in'iproved devicein place on the binding of a book.

The retaining arm 1.? is provided with an enlarged extremity 1Q and'is integral with .LL) the flanged element 21 and stud The helical pring 23 may be partially covered by flange 18 and is conxially positioned on the stud and is secured at its inner extremity as at 24; to the stud and is secured at its outer extremity as at 25, to the enlarged extrcmity 26 oil the arm 27. The enlarged e2;- tremity oil the arm 27 has termed therein an aperture adapted to receive the stud 22, as

a means of pivotally mounting the arm 2/2" tl'rereon. ll1e stud rotatively engagen in an aperture fornledin the mair portion of the bracket '10 and secured thereto, as at 28, preferably by riveting over the extremity ot the stud 22. The above mentioned arms 1? and 27' are provided with enlarged ireeextremiities 1'? and 2?, respectively,formed or bent approximately right angles to "the main portions of the arms. 'lhe above described eonstructicnis such as Will permit the spring to urge the arms in an opposite direction so as to permit the enlarged tree e3-1- tremities of the arms toengage any desired opposite a'lacent pages 291and 30, of an open hook, for-the purpose of securely holding the desired pages in a fully extended position, rendering the reading or perusal of the said desired pages easier and withoutthe necessity of manual assistance. ltis obvious that the ahovedescribed construction is also such ed meinbersfll, pivotally mounted at one end thereof on the pins 32 carried in the lug elements 33 and 34, 01. the arms, 17 and 27 In Figs. 5 and 6, I have shown side QXtGDLh.

positioned at the free extremities thereof, at the rear of the said arms. The coil springs are co-axial on the pins 32 and are provided with extended extremities 36 and 37 adapted to engage the lugs 33 and the ex tended members 31. The above described construction is such as will normally hold the extended members in engagementwith the above mentioned desired opposite adjacent pages of an open book for the purpose as above set forth, and which will permit the extended members to be pivoted or hinged upwardly as at 38, as a means of facilitating the turning of the pages of the book as is advantageous in the reading or perusal of the book.

In Figs. 7 and 8, I have shown a coil spring 39 co-axial on the above mentioned stud '22, intermediate the enlarged extremities 18 and 26 of the arms 17 and 27. The spring 39 is provided with oppositely extended elements 40 and ll, having their extremities formed or bent at 42 and 4-3, respectively adapted to engage the arms 17 and 27, respectively. The above described construction is such will permit the spring 39 to urge the arms in an opposite direction, for the purpose as above set forth.

In Figs. 9, 10, 11 and 12, I have shown the enlarged extremity 26 of the arm 27 having formed or bent therefrom a plurality of radial inwardly extended prong elements 44, adapted to frict-ionally engage in suitable indentures 45 formed in the enlarged extremity 18 of the arm 17. The above described construction is such as Will permit the engagement of the elements -i and 45 to hold the arms 17 and 27 in any desired oppositely extended position, for the purpose as above set forth.

in Fig. 13, I have shown the bracket 10 provided with an extended portion 16 formed or bent downwardly therefrom, at approximately a right angle to the main portion of the said bracket. The extended portion 45 of the bracket 10 is provided with clip elements 4?, 48 and 49, 50, extended respectively from the opposite sides thereof, and adapted to removably engage the edges of the binding 12 of a book, for the purpose as above set forth.

In Fig. 14, I have shown a lever 51, or catch pivotally secured at one extremity thereof, as at 52, intermediately to the arm 17, and adapted. to engage the lug element 53 of the arm 27. The latter described construction is such as will permit my. improved device to be held in a closed position.

Having thus described my invention, what I claim as new and desire to secure by United States Letters Patent is:

1. In a device of the class described, a bracket provided with extended elements adapted to engage the upper portion of the binding of a book as a means of removably holding the device in place on the said book, a pair of arms each pivotally attached to the said bracket, a spring adapted to urge the said arms in opposite directions, said arms provided with enlarged free extremities adapted to engage two opposite adjacentpages of an open book as a means of holding the said pages in an extended position.

A device oi? the ciass described comprising a bracket provided with extended elements adapted to engage the upper portion oi the binding ot a book as a means ofvremovahly holding the device in place on the said book, a pair of arms each pivotally attached to the said bracket, a spring adapted to urge the said arms in opposite direct-ions, said arms provided with enlarged free extremities adapted to engage two opposite adjacent pages of an open book as a n-i-eans of holding the said pages in an extended position.

3. In a device of the class described, a pair oi? arms each pivotally mounted on a stud secured to a bracket, a spring co-axial on the said stud, said spring provided with extended elements having extremities adapted to engage the said pair of arms, as a means of holding the enlarged extremities of the said arms in engagement with any desired opposite adjacent pages of an open book for the purpose of holding the said pages in an extended position.

1. A device of the class described, comprising a bracket for engagement upon the binding of a book, a pair of arms each pivotally attached on the bracket, a means for urging the said arms in opposite directions, andv the said arms being n'ovided with enlarged free extremities for engaging two opposite adjacent pages of an open book as a means for holding the said pages in an extended position.

In testimony whereof I have affixed my signature.
